being had therein to the accompanying drawing.

This invention relates to improvements in plow bodies and especially in those'of the. type adapted for use on steam plows in Which a number of bodies are secured to the same frame. Y

Oneo'f the objects of the invention'is to provide a plow body having improved structural features and improved means for readily and quickly attaching or detaching the plow share to or from the other plow parts. v

Inlthe accompanying drawings I have shown one embodiment of my invention. It is to'be understood, however, thatvarious changes in the construction and arrangement of parts'm'ay be made Within the scope of my invention.

.Of'the drawings, Figure 1 is a perspective view taken from beneath. Fig. 2 is a perspective view taken looking downward from the rear. Fig. 3 is a fragmentary cross sectional view taken on the line 33 of Fig. 1. Fig. 4 is a detailed view of the transverse bracket.

. Referring to the drawings, 1 represents the plow point or share, '2 the moldboard,

'3 the landside, and 4 the frog to which the landside, moldboard and share are connected. 5 is a-standard to which the frog is secured and by means of which the plow body is moved. This standard is indicated by dotted lines in Fig.

The frog is bent or forged in the usual way to provide twoparts atan angle to each other. To one of these parts the moldboard is secured by bolts or rivets and'to the other of these parts the landside' is similarly secured. The plow share 1. has integrally formed moldboard and landside sections. The moldboard section 6 is adapted to be supported by the moldboard part of the frog and to-engagev the forward edge of the moldboard in proper alinement. The landside section 7 is adapted to aline 'with the landside and to engage the landside part of the frog.

On the inner side of the section 7 of the share there is located a lug .8. The lug.

necessarily, form preferably consists of astaple'forniedof a round iron rod, the ends of which are passed through counter-sunk holes in the section 7 and riveted in place. If desired, however,

the projections may be formed integrally with the share,'or in any-other way. -,The frog is provided With a slot 9 into which the lug 8 projects. The engagementof the lug with the edges of the slot prevents any sliding or twistingof the share relativeto the other partsof the plow, body.

10 represents a brace or bracket which extends transversely of theplmvbody. ,At the landside end of the-brace there is formed a lug 11 by means of which the brace may be bolted to the landside. At thefother' end of the brace there -are provided oppositely extending arms 12 and 13,- the former} of, which is engaged by a bolt 1-1 extend ng through the frog, and the, latter of which is engaged by a bolt. 15 extending through the moldboard. At the outer end of the, arm 13 there is provided a forward extension 16 which gradually diminishes in thickness toward its end and "which is provided with a notch 16 adapted to receive the button 17' on the underside of the share. This button 17'is secured to the share by means. of the. bolt 18, thethreaded end of whichis prefer ably riveted over to prevent removal. :The button has a centralhub and an outer flange adapted toclosely engage the under surface of theprojection 16. The hub and flange parts of the button are preferably, but not cated in the drawings.

19 represents a share retaining bolt pivotally secured at its forward end to the uned in one piece, as indider side of the share preferably by means of- I a bolt 20. A notch 21 is formed in'the lower ledge of the brace 10 to receive the rear end of the bolt 19.

Interposed between" the brace 10 and a nut 22 .on the retaining bolt is a latch 23. to theupper side of the brace 10. As'lot 25 permits thelatch to move into the posi- I tion indicated'by full lines in the drawings. \Vhen in thisposition the bolt is held against displacement from the notch21 even though the nut 22 is not tightened. In the preferredconstruction the brace 10 is reinforced by, a lateral flange 26. For reinforcing the brace at the notch 21there is preferably provided a crossflange 27. 28 is a reinforcing flange along the edge of the arm 13 and'the extension 16.

29 is an auxiliary brace secured at one end This latch is pivoted at 24 to the rear part of the moldboard. The

other end of the brace is secured to the. bracket 10 at a point intermediate the land side and the notch 21 To remove the the 'latch';23. to 'be swung indicated by dotted lines in 2. Thebolt 19'may'then besw-ung out of the notch and: the share removed by one floper ation. In replacing the" share it is first is v put in position withthe projection 8 extend-'1 Iinginto the slot 9 and with the button 17 'in'ithe notchhof the bracket extension. 16.

The bolt 1 9 is then swung about its pivot into elanoma 21; After' the latch 23 has been moved'into its normal'bolt retaining ythelug' saithth the share and the"mold boar d so that when" a the boltis tensionedthere isa tendencynot only for movement of the share toward'the" .moldboard but passion, 20'? t e Share 7 v 'It'will be observed that the ngagjement 01E edges'of .the slot 9 pre-' the nut 22: may. be tightened and drawn into its final "position;

jyents'lany relative" movement ofthe share relative" to 'the' landside part of the frog.

The engagement under sideof the' share with the bracket extension l6 prevents'jupward' or downward movement of the share outof aline'ment with vthemoldboard. v

Thesh are retaining bolt 19 is normally at, an angle to' the line of contact between valso for Y movement 'Of" the share transversely of the moldboard toanove the landside section of the share into e"n.
